VoltStorage at a glance
World’s largest operating flow battery fleet
Since the market launch of our residential flow battery system in 2019, we have constantly increased the number of installed systems. Meanwhile, we have the largest fleet of operating flow batteries in the world.
Patented battery manufacturing
With our patented flow battery cell design, we were the first company in the world to succeed in developing a battery cell stack for flow batteries that can be manufactured automatically and thus produced in high numbers.
Iron salt technology
Unrivaled 50€ per kWh: The iron salt technology is destined to shape the future of battery storage beyond lithium, because of the widely available and low-cost iron-based storage medium.
VoltStorage GmbH was founded in 2016 by Jakob Bitner, Michael Peither and Felix Kiefl. Since 2022, Verena Graf has been part of the management team as COO. Together they want to turn the vision into reality of making renewable energy available around the clock to enable a green, sustainable and fair future.
